PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor without causing density variation each time repeating a small number of copies. SOLUTION: The electrophotographic photoreceptor is used in an electrophotographic apparatus which includes a charging means charging the electrophotographic photoreceptor by bringing a charging member into contact with it and which has a process speed equal to or more than 220 mm/second. In the electrophotographic photoreceptor including a conductive support, a charge generation layer containing a charge generation material provided on the conductive support, and a hole transport layer containing a hole transport material provided on the charge generation layer, an intermediate layer or the charge generation layer contains a proper electron conveying compound.
